What is the difference between FreeCAD and OpenSCAD?
FreeCAD and OpenSCAD are both open source CAD software, but they have very different approaches to 3D modelling. FreeCAD is a parametric 3D modeler that uses a sketch-based approach, while OpenSCAD is a script-based modeler that uses a programming language. Here are some of the main differences between them:
- User interface: FreeCAD has a graphical user interface that resembles other commercial CAD software, such as SolidWorks or AutoCAD. It has various workbenches that provide different tools and functions for different tasks, such as Part Design, Draft, Mesh, FEM, etc. OpenSCAD has a non-traditional user interface that consists of a text editor and a 3D preview window. The user has to write code in a custom language to create and modify 3D models, and the preview window only shows the result of the code ¹².
- Modelling method: FreeCAD uses a parametric modelling method, which means that the user can create and edit 3D models by defining sketches, constraints, features, and parameters. The user can also modify the model history and change the parameters at any time. OpenSCAD uses a constructive solid geometry (CSG) method, which means that the user can create and edit 3D models by combining primitive shapes, such as cubes, spheres, cylinders, etc., using boolean operations, such as union, difference, and intersection. The user can also use variables, functions, and loops to create complex shapes ¹².
- Modelling flexibility: FreeCAD offers more modelling flexibility than OpenSCAD, as it supports various types of modelling, such as mechanical engineering, architecture, product design, and 3D printing. It also supports various types of meshes, solvers, and file formats. OpenSCAD is more limited in its modelling capabilities, as it only supports solid modelling and does not support meshes, solvers, or file formats other than STL, DXF, and SVG ¹².
- Modelling precision: OpenSCAD offers more modelling precision than FreeCAD, as it allows the user to define the exact dimensions and coordinates of the shapes using code. It also allows the user to use algorithms and mathematical expressions to create complex and accurate shapes. FreeCAD relies more on the user's graphical input and mouse movements, which can introduce errors and inaccuracies. It also has some issues with rounding errors and tolerance settings ¹².
- Learning curve: FreeCAD has a steeper learning curve than OpenSCAD, as it has a complex and crowded user interface, a large number of tools and functions, and a different workflow for each workbench. The user has to learn how to use the sketcher, the constraints, the features, and the parameters, as well as how to switch between workbenches and modes. OpenSCAD has a simpler and more consistent user interface, a smaller number of tools and functions, and a single workflow for all models. The user only has to learn how to write code in the OpenSCAD language, which is similar to C or Python ¹².
These are some of the main differences between FreeCAD and OpenSCAD, but there are also some similarities and advantages that they share. For example, they are both free and open source, which means that they are constantly updated and improved by the community. They also both have a large and active user base, which means that they have a lot of documentation, tutorials, forums, and support available. They also both have a modular and extensible architecture, which means that they can be customized and enhanced by adding plugins, modules, libraries, and scripts ¹²³⁴..
